“…Beyond identified methodological differences that limit study comparisons according to extraction from either plasma, serum, urine, and/or saliva (Meyer-Bahlburg, 1977), other factors beyond those assessed in our study could further modulate HPG-axis activities. Lastly, the lack of basal endocrine differences according to menstrual status speak to the challenge of self-reports (Bachand et al, 2009;Jukic et al, 2008;Small et al, 2007) that do not consistently correspond with endocrine concentrations presumed to vary according to diverse reproductive statuses. Future studies will need to take special attention to address this issue with more refined control of reproductive functions among both sexes (Juster et al, 2016b).…”

a b s t r a c tThis study assessed sexual orientation and psychobiological stress indices in relation to salivary sex hormones as part of a well-validated laboratory-based stress paradigm. Participants included 87 healthy adults that were on average 25 years old who self-identified as lesbian/bisexual women (n = 20), heterosexual women (n = 21), gay/bisexual men (n = 26), and heterosexual men (n = 20). Two saliva samples were collected fifteen minutes before and fifteen minutes after exposure to a modified Trier Social Stress Test to determine testosterone, estradiol, and progesterone concentrations via enzyme-immune assaying. Mean sex hormones were further tested in association to stress indices related to cortisol systemic output (area under the curve with respect to ground) based on ten measures throughout the two-hour visit, allostatic load indexed using 21 biomarkers, and perceived stress assessed using a well-validated questionnaire. Results revealed that lesbian/bisexual women had higher overall testosterone and progesterone concentrations than heterosexual women, while no differences were found among gay/bisexual men in comparison to heterosexual men. Lesbian/bisexual women and heterosexual men showed positive associations between mean estradiol concentrations and allostatic load, while gay/bisexual men and heterosexual women showed positive associations between mean testosterone and cortisol systemic output. In summary, sex hormone variations appear to vary according to sexual orientation among women, but also as a function of cortisol systemic output, allostatic load, and perceived stress for both sexes. (R.-P. Juster). explanations of non-heterosexual behavior have often hypothesized a dysregulation of sex-specific hormone profiles, resulting in anomalies in the organizational and activational effects of these hormones on the neurodevelopment of circuitry underlying species-specific sexual behavior. Animal models involving prenatal androgen deficits, for example, were first believed to cause male homosexuality (Phoenix et al., 1959), while prenatal androgen overabundance presumably resulted in female homosexuality. Our study endeavours to show that such sex hormone differences assumed to be attributable to sexual orientation are also modulated by unexplored stress phenomena.Advances in behavioral neuroscience has led to the introduction of sophisticated genetic models involving non-functional androgen receptors, further allowing researchers to characterize the relation-Konstanzer Online-Publikations-System (KOPS) URL: http://nbn-resolving. de/urn:nbn:de:bsz:352-2-1f6t7wu8qvgcl6 Erschienen in: Psychoneuroendocrinology ; 72 (2016). -S. 119-130 https://dx.

“…In the present case too, the longest menstrual cycle was found among both the ends of BMI. The women in the present study were distributed in all the categories of BMI, but dominated in 25-35 days duration of menstrual cycle which has been considered to be the regular menstrual cycle length according to Bachand et al [24]. The impact of excess body weight or body fat mass on menstrual cycle has drawn less attention than low body weight.…”

The study aims to see the relationship between menstrual cycle and adiposity measures in Indian populations as menstrual cycle length has an important bearing on fertility and health of women. 415 premenopausal women in the ages 22–50 years residing in Delhi, India constituted the data. The adiposity was assessed by BMI as well as by using Bio-electric impedance method. The information regarding their physical activity pattern and menstrual cycle was recorded, and age at menarche was obtained through recall method. None of the underweight category women had menstrual cycle of less than 25 days. A decrease in body mass index and an increase in the age at menarche were found with the increase in the duration of menstrual cycle. The majority of women with 25–35 days duration of menstrual cycle in the present study were distributed in all the categories of BMI. Age was found to have no effect on longer cycle. The majority of women were in moderately physically active group and experienced menstrual cycle duration of 25–35 days. It is of utmost importance to identify the effects of moderate levels of physical activity, body mass index, and age at menarche on the menstrual cycle to enable the normal reproductive health of women.

Purpose To evaluate the association between menstrual cycle characteristics in early life and adulthood and fecundability. Methods Pregnancy Study Online (PRESTO) is an internet-based preconception cohort study of pregnancy planners from the United States and Canada. During the preconception period, we enrolled 2,189 female pregnancy planners age 21–45 years who had been attempting conception for ≤6 cycles. Women self-reported menstrual cycle characteristics via an online baseline questionnaire, and pregnancy status was ascertained through bi-monthly follow-up questionnaires. Proportional probabilities models were used to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs), adjusting for potential confounders. Results Compared with usual menstrual cycle lengths of 27–29 days, cycle lengths of <25 (FR=0.81, 95% CI: 0.54–1.22) and 25–26 days (FR=0.92, 95% CI: 0.75–1.14) were associated with reduced fecundability. Compared with women who reached menarche at age 12–13 years, those who reached menarche at <12 years had reduced fecundability (FR=0.87, 95% CI: 0.76–0.99). Women whose cycles never regularized after menarche (FR=0.93, 95% CI: 0.81, 1.06) had slightly reduced fecundability compared with women whose cycles regularized within 2 years of menarche. Bleed length and heaviness of bleeding were not appreciably associated with fecundability. Conclusions Menstrual cycle characteristics, specifically cycle length and age at menarche, may act as markers of fertility potential among pregnancy planners.
